I am in the market for a new desktop. It will be used mainly for surfing, emailing, preparing presentations & reports and downloading quite large reports. It will not be used for games or downloading music. How can I future proof the spec for as long as possible? What processor(s) are best? What operating system is best? Is there some major change to Windows XP coming? I was up to date with PCs to about 6 years ago but things have moved ahead that quickly that I have not kept abreast of them. I have been thinking a Mesh computer- has anyone any experience of them? Which model would be recommended? Sorry for all the questions. All info and advice gratefully received.
